Product details
Overview
AUIRF3004WL from Infineon Technologies (formerly International Rectifier) is an automotive-grade N-channel HEXFET Power MOSFET in TO-262 WideLead package, rated for 40 V V(BR)DSS, 1.27 mΩ typ. RDS(on), and 240 A continuous drain current (package-limited). It serves as a high-current, low-loss main switch in 12 V automotive power systems including starter solenoid drivers, battery disconnects, and DC motor control.
For engineers reviewing the AUIRF3004WL datasheet, AUIRF3004WL pinout, AUIRF3004WL application, or AUIRF3004WL equivalent, key selection criteria include its 175°C junction rating, 50% lower lead resistance vs. standard TO-262, repetitive avalanche capability up to 232 A, and RoHS-compliant lead-free construction - all validated for under-hood automotive environments.
Technical Context
This MOSFET employs advanced silicon process technology optimized for low RDS(on) and fast switching in high-current DC applications. Its gate threshold voltage (2.0–4.0 V) enables robust 10 V gate drive compatibility with standard automotive controllers, while the 140–210 nC total gate charge supports efficient PWM operation at frequencies up to 100 kHz.
The integrated body diode exhibits 41–62 ns reverse recovery time and 62–93 nC reverse recovery charge at 25°C, enabling reliable freewheeling in inductive loads. Thermal design is supported by a 0.40 °C/W junction-to-case thermal resistance and validated safe operating area up to 232 A at 25°C case temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | 40 V - Withstands up to 40 V drain-source blocking voltage before avalanche conduction begins. |
| RDS(on) typ. | 1.27 mΩ - Enables <1.3 W conduction loss at 200 A, critical for minimizing heat generation in high-current paths. |
| ID (Package) | 240 A - Maximum continuous drain current limited by package thermal and mechanical constraints, not silicon. |
| TJ max | 175°C - Rated junction temperature allows operation in hot under-hood locations without derating below ambient 125°C. |
| EAS | 2.5 mJ - Single-pulse avalanche energy rating ensures survivability during unclamped inductive switching events. |
| Qg | 140–210 nC - Gate charge range determines required driver strength and switching loss trade-offs in PWM designs. |
| Coss eff. (ER) | 2330 pF - Energy-related output capacitance directly impacts turn-off loss and snubber design in hard-switched topologies. |
Pinout & Package
Supplied in TO-262 WideLead package - a modified TO-262 with widened leads reducing lead resistance by >50% versus standard TO-262, improving current handling and thermal performance in high-power automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G | Gate | Control terminal; requires 10 V drive for full enhancement; internal gate resistance of 2.7 Ω limits dV/dt-induced ringing. |
| D | Drain | Main high-side power terminal; electrically connected to the metal tab (case); must be isolated from heatsink unless referenced to system ground. |
| S | Source | Power return path and reference for gate drive; connects to PCB ground plane or low-side shunt resistor for current sensing. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low on-resistance | 1.27 mΩ typ. RDS(on) minimizes I²R losses in 200+ A load paths, enabling smaller heatsinks and higher efficiency. |
| 50% lower lead resistance | WideLead TO-262 construction reduces parasitic resistance in package leads, lowering voltage drop and localized heating at high current. |
| 175°C junction rating | Supports uninterrupted operation in engine compartment environments where ambient exceeds 125°C, eliminating need for external derating. |
| Repetitive avalanche rated | Validated for repeated unclamped inductive switching up to 232 A, enabling robustness in solenoid and motor drive circuits without snubbers. |
| Automotive qualification | Complies with AEC-Q101 stress test requirements, including HTGB, HTRB, and temperature cycling, ensuring long-term reliability in vehicles. |
Applications
| Starter Solenoid Control | Battery Disconnect Switch |
|---|---|
Use Scenario: High-current engagement of vehicle starter motor via solenoid coil, requiring momentary 200+ A pulses at 12 V. IC Role / Device Role / Timing Role: Main power switch controlling solenoid coil energization; operates in on/off mode with <100 μs switching transitions. Use Value: Low RDS(on) and high avalanche energy prevent failure during coil de-energization transients; 175°C rating ensures reliability near hot engine blocks. | Use Scenario: Isolation of 12 V battery from chassis during service or fault conditions, carrying up to 240 A continuously. IC Role / Device Role / Timing Role: Solid-state replacement for mechanical contactors; functions as bidirectional current-blocking element with fast fault response. Use Value: Package-limited 240 A rating and wide-lead thermal path enable sustained conduction without thermal runaway; RoHS compliance meets modern OEM requirements. |
| DC Motor Drive (HVAC Blower) | Engine Cooling Fan Controller |
Use Scenario: PWM-controlled 12 V blower motor in HVAC system, delivering variable airflow with peak currents exceeding 180 A. IC Role / Device Role / Timing Role: Low-side switching element in half-bridge configuration; switches at 10–20 kHz with controlled dv/dt. Use Value: Fast switching (tr = 220 ns, tf = 130 ns) and low Qg reduce PWM losses; body diode trr < 62 ns supports efficient freewheeling. | Use Scenario: Variable-speed radiator fan driven by 12 V supply, subject to load transients and ambient temperatures up to 105°C. IC Role / Device Role / Timing Role: High-side power switch in fan driver module; handles inrush current and back-EMF during abrupt stops. Use Value: Repetitive avalanche rating absorbs inductive kickback without external clamping; 0.40 °C/W RθJC simplifies thermal interface design on compact modules. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N4F7AG | 40 V, 220 A (package-limited), 1.35 mΩ RDS(on), TO-263 package | Lacks automotive qualification; lower avalanche rating (1.8 mJ EAS); no wide-lead thermal advantage | Acceptable for non-automotive industrial 12 V systems where AEC-Q101 is not mandated. |
| IRFB4115PBF | 150 V, 110 A, 4.5 mΩ RDS(on), TO-220 package, 175°C rated | Higher voltage rating but significantly higher RDS(on); unsuitable for 240 A conduction due to thermal limits | Only viable if system requires >40 V blocking; otherwise excessive conduction loss and insufficient current capacity. |
Compared with STL220N4F7AG and IRFB4115PBF, the AUIRF3004WL uniquely combines automotive qualification, 240 A package-limited current, ultra-low 1.27 mΩ RDS(on), and wide-lead thermal performance - making it irreplaceable in space-constrained, high-reliability 12 V automotive power switching.

FAQ
What is the maximum continuous drain current for AUIRF3004WL at 100°C case temperature?
At TC = 100°C, the continuous drain current is 273 A (silicon-limited) per the datasheet's Absolute Maximum Ratings table. However, the package-limited rating remains 240 A regardless of temperature - meaning thermal design must ensure case temperature stays ≤85°C to sustain full 240 A without derating.
Does AUIRF3004WL require a gate resistor for automotive PWM operation?
Yes - a series gate resistor (typically 2.7–10 Ω) is recommended to dampen ringing caused by PCB trace inductance and the device's 2.7 Ω internal gate resistance. This controls dv/dt during switching and prevents false turn-on due to Miller effect, especially critical in noisy automotive environments.
Can AUIRF3004WL be used in parallel configurations for >240 A applications?
Parallel operation is feasible but requires careful layout: matched gate drive paths, symmetrical source routing, and individual Kelvin-source connections to ensure current sharing. The positive RDS(on) temperature coefficient (see Fig. 4) provides inherent thermal stability, but thermal coupling between devices must be minimized to avoid hotspot formation.
Is the TO-262 WideLead package compatible with standard TO-262 footprints?
No - the WideLead variant has wider leads and altered lead pitch versus standard TO-262. PCB land patterns must be updated to match the manufacturer's specified outline (see www.infineon.com/AUIRF3004WL/package-drawing). Using a standard TO-262 footprint risks solder joint fatigue and increased thermal resistance due to poor lead contact area.
